“zenzen・mattaku・sukoshi mo 〜nai”: Not at All 〜 (total negation adverbs) [JLPT N4]

Content by NTJ Kuma · Nihongo to Japan editorial team · Updated July 27, 2026

“don't understand at all,” “exactly the same,” “not the least bit happy” — three “completely” adverbs

「全然わからない」 — the complete-negation adverbs “not at all”

「この問題全然わからない」 (I don't get this at all) — 「全然・まったく・少しも」 are adverbs paired with a negative to mean “not at all, not in the least.” They're not an ordinary “not,” but a complete, thorough negation (not just “don't understand,” but “not at all”). This guide covers these emphatic-negation adverbs, their nuances, and clarifies the 「全然 + affirmative」 controversy.

Core: complete, thorough negation (not in the least)

These adverbs + a negative = “not at all, not in the least” (stressing a degree of zero):

Common thread: always paired with a negative (〜ない, 〜ません), meaning “zero, utterly none.”

How to Connect

ぜんぜん + affirmative(colloquial) totally (controversial)全然大丈夫

Examples in context

⚠️ Where learners slip up

Always paired with a negative (the exam standard). 全然・まったく・少しも take a negative (全然わからない, まったくない). ✗ 全然おいしい (marked wrong on exams). For “very,” use 「とても」. (Though colloquial 「全然 + affirmative」 exists, see below.)

「全然 + affirmative」 is a colloquial phenomenon. Daily speech has 「全然大丈夫 (totally fine)」, 「全然いい (super good)」, meaning “totally, very (positive).” Common among young people, but formal/exam still treats “全然 + negative” as standard. Fine colloquially; avoid in writing/exams.

Degree differences. 全然 (colloquial, common) < まったく (stronger, formal); 「少しも/ちっとも〜ない」 stress “not even a bit” (少しも = not in the least, ちっとも = the colloquial version). To strengthen a negative, use まったく or 少しも.

🔄 Nuance & comparison: 全然/まったく/少しも

FormNuanceExample
全然〜ないnot at all (colloquial, common)全然わからない (I don't understand at all.)
まったく〜ないnot at all (strong, formal)まったく興味がない (I have absolutely no interest.)
少しも/ちっとも〜ないnot in the least (stresses zero)少しも怖くない (I'm not the least bit scared.)
あまり〜ないnot very ~ (partial negation)あまり好きじゃない (I don't like it much.)

💡 The one thing to remember

「全然・まったく・少しも」 are all emphatic-negation adverbs for “not at all, not in the least,” always with a negative. They differ in strength and register: 全然 (most colloquial, common) → まったく (stronger, formal) → 少しも/ちっとも (stress “not even a bit”). Practical point: don't confuse with 「あまり〜ない (not very)」 — 全然わからない = don't get it at all (zero), あまりわからない = don't get it much (a bit). One controversy: colloquial 「全然 + affirmative」 (全然大丈夫 = totally fine) is super common daily, but formal/exam still holds “全然 + negative” as standard. 「全然OK」 is fine in chat; keep 「全然〜ない」 for writing/exams. This set makes negation thorough and native.

❓ Common questions

Q: Can 「全然」 take an affirmative? (全然大丈夫)

Depends on colloquial vs exam. Traditional/exam standard: 「全然」 takes a negative (全然わからない = don't get it at all, 全然ない = none at all). But in modern speech, 「全然 + affirmative」 is common, meaning “totally, very (positive)”: 全然大丈夫 (totally fine), 全然いい (super good), 全然おいしい (very tasty). It's widespread in daily conversation (especially among young people) and widely accepted. Bottom line: 「全然 + affirmative」 is fine in chat, but formal writing and JLPT still safely hold “全然 + negative.”

Q: How do I tell 「全然」「まったく」「少しも」 apart?

All mean “not at all,” differing in strength and register. 「全然〜ない」 = not at all (most colloquial, common): 全然わからない (don't get it at all). 「まったく〜ない」 = not at all, not in the slightest (stronger, more formal/written): まったく興味がない (no interest at all), まったく問題ない (no problem at all). 「少しも/ちっとも〜ない」 = not in the least, not even a bit (stressing “zero”): 少しも怖くない (not scared in the least), ちっとも (colloquial version). Degree: 全然 (general) < まったく (strong); 少しも/ちっとも specially stress “not a shred.” All take a negative. For “not very” (partial negation, still a bit) use 「あまり〜ない」 — don't mix it with this (complete-negation) set.
